Description

Technical Field

[0001] The present invention relates to the technical field of clothing treatment, and specifically provides a double-pump assembly and a clothing treatment apparatus including the double-pump assembly.

Background Art

[0002] As people's living standards have been increasing, the application of washing machines has become increasingly widespread. Taking a drum washing machine as an example, a drum washing machine usually includes a housing, a drum component located within the housing, and a waterway system. The drum component usually includes an inner drum and an outer drum that communicate with each other, and the inner drum can rotate relative to the outer drum. The waterway system includes a water supply hose, and tap water enters the inner drum through the water supply hose. During washing, the clothing to be washed in the inner drum is repeatedly lifted and dropped, and the action of detergent and washing water is applied thereto to achieve the purpose of washing the clothing. The waterway system further includes a drainage hose and a drainage pump installed on the drainage hose. After the rinsing stage and the dehydration stage, the washing water in the outer drum can be discharged from the drainage hose by the action of the drainage pump.

[0003] In order to meet people's increasingly high requirements for the functionality, environmental protection, washing rate, etc. of washing machines, the waterway system further includes a circulation hose and a circulation pump installed on the circulation hose. One end of the circulation hose is connected to the drainage port of the outer drum, and the other end is connected to the circulation water inlet of the outer drum. By flowing the water at the bottom of the outer drum to the top of the outer drum via the circulation hose by the action of the circulation pump, the circulating flow of the washing water is realized, and the washing rate of the washing machine is increased.

[0004] However, adding an extra circulation pump, along with the corresponding piping and valves, would inevitably increase the cost of the drum washing machine. Furthermore, the independent installation of the circulation and drainage pumps would require them to occupy a significant amount of space inside the drum washing machine. The need to install each of the two water pumps individually during assembly would increase the production process and reduce production efficiency. The noise generated by each of the two pumps during washing would also be relatively loud.

[0005] Accordingly, in this field of technology, new technological solutions are needed to address the above-mentioned problems. [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] The present invention aims to solve the above-mentioned technical problems, namely, the problems that arise in conventional drum washing machines, where the circulation pump and drainage pump are installed independently of each other, requiring a large amount of space to be occupied, resulting in low production efficiency, high noise levels, and high costs.

[0011] In the preferred technical application of the double pump assembly described above, the pump body is provided with a first mounting port communicating with the first water supply chamber, and the first filtration component includes a first screw cover fitted into and connected to the first mounting port, and a first filtration member having a first end connected to the first screw cover and a second end connected to the first through-hole.

[0012] In the preferred technical application of the double pump assembly described above, the double pump assembly further includes a second filtration component that is removably installed on the pump body, wherein the second water supply chamber and the second drainage chamber are connected by a second through-hole, and the second filtration component is installed to filter the water entering the second drainage chamber through the second through-hole.

[0013] In the preferred technical application of the double pump assembly described above, the pump body is provided with a second mounting port communicating with the second water supply chamber, and the second filtration component includes a second screw cover fitted into and connected to the second mounting port, and a second filtration member having a first end connected to the second screw cover and a second end connected to the second through-hole.

[0014] In the preferred technical application of the double pump assembly described above, the first filtration member includes a first base, a first filter rod and a first filter barrel mounted on the first base, the first base being connected to a first screw cap, the end of the first filter rod away from the first base being inserted into the first filter barrel via a first end of the first filter barrel, and the second end of the first filter barrel being connected to a first through hole, and the second filtration member includes a second base and a second filter rod mounted on the second base.

[0015] In the preferred technical application of the double pump assembly described above, the double pump assembly further includes a mounting component connected to a target part, the pump body being mounted to the target part via the mounting component, and / or the pump body being further provided with a drain that communicates with the first water supply chamber or the second water supply chamber. Beneficial effect

[0016] In the proposed technical version of the present invention, the double pump assembly includes a pump body, a first pump head component installed on the pump body, and a second pump head component, wherein a first water supply chamber and a second water supply chamber communicating with each other are installed inside the pump body, and the pump body is provided with a water inlet, a first drain port, and a second drain port, the water inlet communicating with the first water supply chamber or the second water supply chamber, so that external water can enter the first water supply chamber or the second water supply chamber via the water inlet, and then enter the second water supply chamber from the first water supply chamber, or enter the first water supply chamber from the second water supply chamber. The first pump head component is installed so that water that enters the first water supply chamber via the water inlet can be discharged via the first drain port, and the second pump head component is installed so that water that enters the second water supply chamber via the water inlet can be discharged via the second drain port. This invention integrates two pumps by installing one water inlet, two drainage ports, and two pump head components, enabling two different, mutually non-interfering flow paths with a single pump body. Compared to installing two pumps individually, the mounting space required for the double pump assembly of this invention is relatively small, and because one water inlet and one pump body are eliminated, the number of related parts is also reduced, making installation easier and lowering costs. Furthermore, since each pump head component corresponds to one flow path, the operating efficiency of the pump head components can be better matched to the flow path conditions, and the noise generated during operation is also reduced.

[0017] Furthermore, an intermediate chamber is installed within the pump body, positioned between the first and second water supply chambers to connect them. In this way, regardless of the location of the water inlet within the pump body, which water supply chamber it connects to, or the amount of water, the water enters the pump body through the inlet and then flows smoothly to the first or second water supply chamber as needed, ensuring stable operation regardless of which pump head component is switched on.

[0018] Furthermore, a first drain chamber and a second drain chamber are installed within the pump body, with the first drain chamber communicating with the first water supply chamber, the second drain chamber communicating with the second water supply chamber, the first drain port communicating with the first drain chamber, and the second drain port communicating with the second drain chamber. In this way, through the action of the first or second pump head component, external water enters the first or second water supply chamber from the water supply port, then enters the first or second drain chamber from the first or second water supply chamber, and is discharged from the first or second drain port. By ensuring the continuity of drainage from the first and second drain ports in this manner, the operational continuity of the double pump assembly can be ensured.

[0019] Furthermore, the double pump assembly further includes a first filtration component and a second filtration component, both of which are detachably mounted on the pump body, with a first water supply chamber and a first drainage chamber connected by a first through-hole, and a second water supply chamber and a second drainage chamber connected by a second through-hole, the first filtration component being configured to filter water entering the first drainage chamber through the first through-hole, and the second filtration component being configured to filter water entering the second drainage chamber through the second through-hole. In this way, while the double pump assembly is in operation, water coming out of the first drainage port first enters the first filtration component for treatment, and water coming out of the second drainage port first undergoes filtration by the second filtration component, thereby ensuring the cleanliness of the water coming out of the first and second drainage ports and meeting the water quality requirements of each waterway. After the first and second filtration components become dirty, they can be removed, cleaned, and replaced, thereby ensuring better filtration efficiency. Moreover, since filtration components are installed in each of the two water channels, the specific types of the first and second filtration components can be selected according to specific needs, better meeting the water quality requirements of the different water channels.

[0020] Furthermore, the pump body is provided with a first mounting port communicating with a first water supply chamber and a second mounting port communicating with a second water supply chamber. The first filtration component includes a first screw cover fitted into and connected to the first mounting port, and a first filtration member whose first end is connected to the first screw cover and whose second end is connected to the first through-hole. The second filtration component includes a second screw cover fitted into and connected to the second mounting port, and a second filtration member whose first end is connected to the second screw cover and whose second end is connected to the second through-hole. In this way, the first and second filtration members can be installed through the first and second through holes, respectively. The water in the first water supply chamber is filtered by the first filtration member before entering the first drainage chamber, and the water in the second water supply chamber is filtered by the second filtration member before entering the second drainage chamber. This ensures the cleanliness of the water entering the first and second drainage chambers, thereby meeting the water quality requirements of each waterway.

[0021] Furthermore, the first filtration member includes a first base, a first filtration rod installed on the first base, and a first filtration barrel, wherein the first base is connected to a first screw cap, the end of the first filtration rod away from the first base is inserted into the first filtration barrel via a first end of the first filtration barrel, and the second end of the first filtration barrel is connected to a first through hole. The second filtration member includes a second base, a second filtration rod installed on the second base, and a second filtration barrel, wherein the second base is connected to a second screw cap, the end of the second filtration rod away from the second base is inserted into the second filtration barrel via a first end of the second filtration barrel, and the second end of the second filtration barrel is connected to a second through hole. In this way, as the water flows through the first and second filtration members, the first and second filtration rods first catch cotton, fibers, and other materials in the water. Then, the water flows into the first and second drainage chambers via the gaps between the first filtration rod and the inner wall of the first end of the first filtration barrel, and between the second filtration rod and the inner wall of the first end of the second filtration barrel. Because the gaps between the first filtration rod and the inner wall of the first end of the first filtration barrel, and between the second filtration rod and the inner wall of the first end of the second filtration barrel are both small, the impurities in the water are further filtered out, resulting in a good filtration effect.

[0022] The height of the first filter barrel is less than or equal to that of the second filter barrel, and the gap between the second filter rod and the inner wall of the first end of the second filter barrel is less than or equal to the gap between the first filter rod and the inner wall of the first end of the first filter barrel. In this way, water entering the second water supply chamber has its flow velocity reduced before flowing out through the second filter barrel, and because the gap between the second filter rod and the inner wall of the first end of the second filter barrel is smaller, impurities such as gravel and peony in the water can be filtered more effectively. Thus, the second filtration component can achieve a better filtration effect than the first filtration component, that is, the purity of the water coming out of the second outlet is higher. When using the double pump assembly of the present invention, a water channel with a higher requirement for water cleanliness may be connected to the second outlet, thereby better satisfying the filtration requirements.

[0023] According to a second aspect of the present invention, there is further provided a clothing treatment apparatus including the double pump assembly according to any one of the above items.

[0024] It should be noted that the clothing treatment apparatus has all the technical effects of the double pump assembly, and will not be described further herein.

Modes for Carrying Out the Invention

[0026] Preferred embodiments of the present invention will be described below with reference to the drawings. Those skilled in the art will understand that these embodiments are solely for the purpose of interpreting the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. In these embodiments, a drum-type washing machine has been discussed as an example, but it is clear that the invention can also be applied to other types of garment processing equipment, such as swirl-type washing machines and washer-dryers, or to other cases where the double pump assembly of this application is required.

[0027] It should be explained that in the description of this invention, terms indicating direction or positional relationships such as "up," "down," "left," and "right" are based on the directions or positional relationships shown in the drawings and are merely for the purpose of facilitating description. They do not indicate or imply that the device or element necessarily has a specific orientation, or that it is composed and operated in a specific orientation, and therefore should not be understood as limitations on the invention. Furthermore, the terms "first," "second," "third," "fourth," "fifth," "sixth," "seventh," and "eighth" are merely for descriptive purposes and should not be understood as indicating or implying relative importance.

[0028] To meet people's increasingly high demands for washing machine functionality, environmental protection, and cleaning efficiency, drum-type washing machines are equipped with a circulation pump that circulates water from the bottom of the outer drum to the top, thereby improving the cleaning efficiency of the washing machine. However, this requires the installation of one circulation pump and one drain pump in the drum washing machine, occupying a significant amount of space, making installation very inconvenient, increasing costs, and generating relatively high noise during operation. Therefore, the double pump assembly of the present invention includes one water inlet, two drain outlets, and two pump head components, integrating two pumps and realizing two different, non-interfering flow paths with a single pump body. Compared to installing two pumps individually, the double pump assembly of the present invention requires less installation space, has fewer related parts, is easier to install, is less expensive, and generates relatively low noise during operation.

[0029] The following discussion will describe possible realizations of the double pump assembly of the present invention and a drum-type washing machine equipped with the double pump assembly, using Figures 1 to 3 together.

[0030] As shown in Figures 1 and 2, and according to the orientation shown in Figure 2, the double pump assembly includes a pump body 10, a first pump head component 20, and a second pump head component 30, the first pump head component 20 and the second pump head component 30 being installed in the pump body 10 by means of engagement or screw connection. Inside the pump body 10 are a first water supply chamber 102 and a second water supply chamber 103 that communicate with each other, with the first water supply chamber 102 located on the left and the second water supply chamber 103 located on the right. The pump body 10 is equipped with a water inlet 101, a first drain port 104, and a second drain port 105. The water inlet 101 communicates with the first water supply chamber 102, so that external water can enter the first water supply chamber 102 via the water inlet 101 and then enter the second water supply chamber 103 from the first water supply chamber 102. The first pump head component 20 includes a first drive mechanism 201 and a first impeller (not shown) connected to the first drive mechanism 201. When the first pump head component 20 is in operation, the first drive mechanism 201 operates to rotate the first impeller, and the rotation of the first impeller draws external water into the first water supply chamber 102 via the water inlet 101 and then discharges it from the first drain port 104. The second pump head component 30 includes a second drive mechanism 301 and a second impeller (not shown) connected to the second drive mechanism 301. When the second pump head component 30 is in operation, the second drive mechanism 301 operates to rotate the second impeller. The rotation of the second impeller draws external water into the first water supply chamber 102 via the water inlet 101, then into the second water supply chamber 103, and finally discharges it from the second drain port 105. In this way, by installing one water inlet 101, two drain ports, and two pump head components on the pump body 10, two pumps are integrated, and two different, mutually non-interfering flow paths can be realized with just one pump body 10.Compared to installing two pumps individually, the double pump assembly of the present invention requires relatively little mounting space, and by eliminating one water inlet 101 and one pump body 10, the number of related parts is reduced, making installation easier and lowering costs. Furthermore, each pump head component corresponds to one flow path, thus allowing the operating efficiency of the pump head component to be better matched to the flow path conditions, and the noise generated during operation is also relatively low. In this invention, the upper edge of the water inlet 101 of the double pump assembly is substantially flush with the upper wall of the first water chamber 102, and its radial dimension is slightly smaller than the height of the first water chamber 102 and the second water chamber 103. In this way, when the double pump assembly is in operation, the water that enters the pump body 10 through the water inlet can fill the first water chamber 102 and the second water chamber 103. In this way, the presence of air in the first water chamber 102 and the second water chamber 103 can be prevented from causing air trapping, thereby allowing for better control of the flow rate in each flow path and reducing noise generated during operation. Moreover, since water can fill the first water supply chamber 102 and the second water supply chamber 103, a smooth start can be ensured during the initial startup of the double pump assembly, water can be drained smoothly from the first drain port 104 and the second drain port 105, and drainage will not be disrupted because there is air in the first water supply chamber 102 and the second water supply chamber 103.

[0031] It should be explained that the water inlet 101 may be connected to the second water supply chamber 103. In this case, when the first pump head component 20 is in operation, the external water first enters the second water supply chamber 103 through the water inlet 101, then enters the first water supply chamber 102 through the second water supply chamber 103, and is then discharged from the first drain port 104.

[0032] For the sake of clarity, the double pump assembly of the present invention will be discussed below, with reference to Figures 1 to 3, using the example that the water inlet 101 communicates with the first water supply chamber 102.

[0033] As shown in Figures 1 to 3, and following the orientation shown in Figure 2, an intermediate chamber 106 is further installed inside the pump body 10. This intermediate chamber 106 is located between the first water supply chamber 102 and the second water supply chamber 103, with one end communicating with the first water supply chamber 102 and the other end communicating with the second water supply chamber 103. In this way, the intermediate chamber 106 connects the first water supply chamber 102 and the second water supply chamber 103 to each other. The intermediate chamber 106 has a roughly elongated cylindrical structure, and its radial dimension is approximately the same as the radial dimension of the water inlet 101. In this way, when the second pump head component 30 is in operation, external water is drawn into the first water supply chamber 102 via the water inlet 101, then enters the second water supply chamber 103 via the intermediate chamber 106, and then discharged from the second drain port 105. In this case, the radial dimension of the intermediate chamber 106 is relatively large, and the upper and lower sides of its inner wall are almost flush with the upper and lower sides of the inner walls of the first water supply chamber 102 and the second water supply chamber 103. Thus, the water that enters the pump body from the water inlet 101 can fill the first water supply chamber 102 and the second water supply chamber 103. In this way, the desired water flow rate can be achieved without increasing the operating efficiency of the second pump head component 30. Furthermore, the presence of air in the first water supply chamber 102 and the second water supply chamber 103 can be prevented from causing air trapping. Because the radial dimension of the intermediate chamber 106 is relatively small, the water flow does not become too fast in the intermediate chamber 106, causing noise. This allows for better control of the flow rate in each flow path, reduces noise generated during operation, and ensures stable, low-noise operation of the double pump assembly. Clearly, the radial dimension of the intermediate chamber 106 may be larger than the radial dimension of the water inlet 101. Of course, the radial dimension of the intermediate chamber 106 may also be smaller than the radial dimension of the water inlet 101; however, in this case, there is a possibility that the noise generated during operation will be large due to the relatively small radial dimension of the intermediate chamber 106.

[0034] It should be explained that the pump body 10 may not have an intermediate chamber 106, and communication between the first water supply chamber 102 and the second water supply chamber 103 may be achieved by a single connecting hose. However, it is preferable that the diameter of the connecting hose is close to the diameter of the water inlet 101. Otherwise, the water flow through the connecting hose is likely to generate noise, reducing the user experience.

[0035] As shown in Figures 1 to 3, and following the orientation shown in Figure 2, a first drain chamber 107 and a second drain chamber 108 are further installed inside the pump body 10. The first drain chamber 107 is located above the first water supply chamber 102 and communicates with the first water supply chamber 102, the second drain chamber 108 is located above the second water supply chamber 103 and communicates with the second water supply chamber 103, the first drain port 104 communicates with the first drain chamber 107, and the second drain port 105 communicates with the second drain chamber 108. The first impeller is inserted into the first drain chamber 107, and the second impeller is inserted into the second drain chamber 108. Through the action of the first pump head component 20 or the second pump head component 30, external water enters the first water supply chamber 102 or the second water supply chamber 103, then enters the first drain chamber 107 or the second drain chamber 108 from the first water supply chamber 102 or the second water supply chamber 103, and is then discharged from the first drain port 104 or the second drain port 105. In this way, when the first pump head component 20 or the second pump head component 30 is in operation, water is always retained in the first drain chamber 107 and the second drain chamber 108, and by ensuring the continuity of drainage from the first drain port 104 and the second drain port 105, the operational continuity of the double pump assembly can be ensured.

[0036] It should be explained that only the first drainage chamber 107 or the second drainage chamber 108 may be installed inside the pump body 10. It is clear that the first drain chamber 107 and the second drain chamber 108 do not necessarily have to be installed inside the pump body 10. In this case, the pump body 10 may only contain the first water supply chamber 102 and the second water supply chamber 103, with the first drain port 104 communicating with the first water supply chamber 102 and the second drain port 105 communicating with the second water supply chamber 103. The first impeller of the first pump head component 20 extends into the first water supply chamber 102, and the second impeller of the second pump head component 30 extends into the second water supply chamber 103. When the first pump head component 20 is in operation, it is possible to draw in external water into the first water supply chamber 102 and then discharge it from the first drain port 104. When the second pump head component 30 is in operation, it is also possible to draw in external water into the second water supply chamber 103 and then discharge it from the second drain port 105. However, because the first drainage chamber 107 and the second drainage chamber 108 are not installed, problems may occur during operation, such as discontinuity in drainage from the first drain outlet 104 and the second drain outlet 105, or increased noise due to bubbles being present in the water discharged from the first drain outlet 104 and the second drain outlet 105.

[0037] As shown in Figures 1 to 3, the double pump assembly further includes a first filtration component 40 and a second filtration component 50, both of which are removablely installed in the pump body 10. A first through-hole 111 is provided between the first water supply chamber 102 and the first drainage chamber 107, and the two are connected by the first through-hole 111. A second through-hole 112 is provided between the second water supply chamber 103 and the second drainage chamber 108, and the two are connected by the second through-hole 112. The first filtration component 40 is installed to filter water that enters the first drainage chamber 107 through the first through-hole 111, and the second filtration component 50 is installed to filter water that enters the second drainage chamber 108 through the second through-hole 112. Thus, during operation of the double pump assembly, water coming out of the first outlet 104 first enters the first filtration component 40 for treatment, and water coming out of the second outlet 105 first undergoes filtration by the second filtration component 50. In this way, the cleanliness of the water coming out through the first outlet 104 and the second outlet 105 is ensured, and the water quality requirements of each channel can be met. Since the first filtration component 40 and the second filtration component 50 are detachably installed on the pump body 10, they can be easily removed, cleaned, and replaced after they become dirty, thereby better ensuring the filtration effect. Moreover, since filtration components are installed in each of the two channels, the specific types of the first filtration component 40 and the second filtration component 50 can be selected according to specific needs, thus better meeting the water quality requirements of the different channels.

[0038] It should be explained that the double pump assembly may further include only the first filtration component 40 or only the second filtration component 50. For example, if the double pump assembly includes only the first filtration component 40, then the water discharged through the second outlet 105 will not undergo filtration, and the water in the channel will not meet the water quality requirements. Clearly, the double pump assembly does not need to include both the first filtration component 40 and the second filtration component 50. In this case, the water entering the pump body 10 will not undergo filtration and will be discharged through the first outlet 104 and the second outlet 105, resulting in a problem where the water quality requirements cannot be met.

[0039] As shown in Figures 1 to 3, the pump body 10 is provided with a first mounting port 109 and a second mounting port 110. The first filtration component 40 includes a first screw cover 401 and a first filtration member 402. A first arc-shaped segment 4011 is provided on the outer edge of the first screw cover 401, and a second arc-shaped segment 1091 that fits into the first arc-shaped segment 4011 is provided on the inner wall of the first mounting port 109. The fitting of the first arc-shaped segment 4011 and the second arc-shaped segment 1091 realizes a fitting connection between the first screw cover 401 and the first mounting port 109. The first end of the first filtration member 402 is connected to the first screw cover 401, and the second end of the first filtration member 402 is connected to the first through hole 111. The second filtration component 50 includes a second screw cover 501 and a second filtration member 502. A third arc-shaped segment 5011 is installed on the outer edge of the second screw cover 501, and a fourth arc-shaped segment 1101 is installed on the inner wall of the second mounting opening 110, which fits into the third arc-shaped segment 5011. The fitting of the third arc-shaped segment 5011 and the fourth arc-shaped segment 1101 achieves a fitted connection between the second screw cover 501 and the second mounting opening 110. The first end of the second filtration member 502 is connected to the second screw cover 501, and the second end of the second filtration member 502 is connected to the second through hole 112.

[0040] Thus, during installation, the first and second filtration members are first connected to the first screw cover 401 and the second screw cover 501, respectively. Then, the first arc-shaped segment 4011 is aligned to the part of the inner wall of the first mounting opening 109 other than the second arc-shaped segment 1091, and the first screw cover 401 is rotated to fit the first arc-shaped segment 4011 and the second arc-shaped segment 1091 together. The third arc-shaped segment 5011 is then aligned to the part of the inner wall of the second mounting opening 110 other than the fourth arc-shaped segment 1101, and the second screw cover 501 is rotated to fit the third arc-shaped segment 5011 and the fourth arc-shaped segment 1101 together, thereby completing the installation of the first filtration member. The first screw cover 401 and the second screw cover 501 are attached so as to engage and connect to the first mounting opening 109 and the second mounting opening 110. In this way, the first filter member 402 and the second filter member 502 can be installed in the first through-hole 111 and the second through-hole 112, respectively. The water in the first water supply chamber 102 is filtered by the first filter member 402 before entering the first drainage chamber 107, and the water in the second water supply chamber 103 is filtered by the second filter member 502 before entering the second drainage chamber 108. This ensures the cleanliness of the water entering the first drainage chamber 107 and the second drainage chamber 108, and satisfies the water quality requirements of each waterway.

[0041] It should be explained that the first screw cover 401 can be fitted and connected to the first mounting port 109 by methods such as screwing and bonding, and the second screw cover 501 can also be fitted and connected to the second mounting port 110 by methods such as screwing and bonding. Without departing from the principles of this application, a person skilled in the art can flexibly select the specific method of fitting and connecting the first screw cover 401 to the first mounting port 109 and the second screw cover 501 to the second mounting port 110 depending on the specific application scene, and it is sufficient that the first filtration member 402 and the second filtration member 502 are installed in the pump body 10 by the first screw cover 401 and the second screw cover 501 to obtain a good filtration effect.

[0042] As shown in Figures 1 to 3, and following the orientation shown in Figure 2, the first mounting port 109 communicates with the first water supply chamber 102, and the second mounting port 110 communicates with the second water supply chamber 103. The first mounting port 109 is located at the bottom of the pump body 10 and faces the first through hole 111, and the second mounting port 110 is located at the bottom of the pump body 10 and faces the second through hole 112. It is clear that the first mounting port 109 and the second mounting port 110 do not necessarily have to face the first through hole 111 and the second through hole 112.

[0043] The first filtration member 402 includes a first base 4021, a first filtration rod 4022, and a first filtration barrel 4023. The first base 4021 has a frustoconical structure that is convex upwards, and a first flange 40211 extends outward from the lower end of the first base 4021, with the first flange 40211 extending outward along the horizontal direction. The first base 4021 has a second flange 40212 installed above the first flange 40211, with the second flange 40212 extending outward along the horizontal direction. Both the first flange 40211 and the second flange 40212 are installed along the circumferential direction of the first base 4021, and the first flange 40211 and the second flange 40212 form a first locking structure. The first screw cover 401 includes a first screw cover body 4012, the first handle end 4013 extending downward from the lower surface of the first screw cover body 4012, and the first arc-shaped segment 4011 being installed on the circumferential outer wall of the first screw cover body 4012. A first flap 4014 is installed on the upper surface of the first screw cover body 4012, the first flap 4014 extending inward along the horizontal direction, the first flap 4014 being installed along the circumferential direction of the first screw cover 401, the first flap 4014 and the upper surface of the first screw cover body 4012 forming a first locking point, and the first locking structure can be locked and installed up to the first locking point. The first filter rod 4022 and the first filter barrel 4023 are both installed vertically, with the diameter of the first filter rod 4022 gradually decreasing from bottom to top, and the diameter of the first filter barrel 4023 gradually increasing from bottom to top. The lower end of the first filter rod 4022 is connected to the upper side of the first base 4021, and the upper end of the first filter rod 4022 is inserted into the first filter barrel 4023 via the first end of the first filter barrel 4023 (i.e., the lower end of the first filter barrel 4023 in Figure 2). In this way, the gap between the first filter rod 4022 and the first filter barrel 4023 also gradually increases from bottom to top, without affecting the normal flow of water.The first filtration member 402 further includes a first connecting member 4024, which has a substantially flat structure, with a first end of the first connecting member 4024 (i.e., the lower end of the first connecting member 4024 in Figure 2) connected to the first base 4021, and a second end (i.e., the upper end of the first connecting member 4024 in Figure 2) connected to the first filtration barrel 4023, thus achieving a connection between the first filtration barrel 4023 and the first base 4021. A third flange 40231 and a fourth flange 40232 extend outward from the second end of the first filtration barrel 4023 (i.e., the upper end of the first filtration barrel 4023 in Figure 2), and these third flanges 40231 and 40232 are distributed along the circumferential direction of the first filtration barrel 4023. The fourth flange 40232 is connected to the second end of the first connecting member 4024, and the first annular boss 40233 extends upward from the upper surface of the third flange 40231. The second annular boss 1111 extends downward from the inner edge of the first through hole 111, with the outer diameter of the second annular boss 1111 being approximately the same as the inner diameter of the first annular boss 40233, so that when the installation is complete, the first annular boss 40233 covers the outside of the second annular boss 1111. When installing the first filtration component 40, first the first locking structure is locked to the first locking point, thereby setting the first base 4021 to engage and connect with the first screw cover 401. Then the first filter barrel 4023 and the first filter rod 4022 are pushed into the first water supply chamber 102, and an upward external force is applied to connect the first annular boss 40233 to the second annular boss 1111. Then an external force is applied to the first handle end 4013 to rotate the first screw cover 401, and the first screw cover 401 is installed to engage and connect with the first mounting opening 109. In this way, the first filtration component 40 is installed inside the first water supply chamber 102.

[0044] The second filtration member 502 includes a second base 5021, a second filtration rod 5022, and a second filtration barrel 5023. The second base 5021 has a frustoconical structure that is convex upwards, and a fifth flange 50211 extends outward from the lower end of the second base 5021, with the fifth flange 50211 extending outward along the horizontal direction. The second base 5021 has a sixth flange 50212 installed above the fifth flange 50211, with the sixth flange 50212 extending outward along the horizontal direction. Both the fifth flange 50211 and the sixth flange 50212 are installed along the circumferential direction of the second base 5021, and the fifth flange 50211 and the sixth flange 50212 form a third locking structure. The second screw cover 501 includes a second screw cover body 5012, with a second handle end 5013 extending downward from the lower surface of the second screw cover body 5012, and a third arc-shaped segment 5011 installed on the circumferential outer wall of the second screw cover body 5012. A second flap 5014 is installed on the upper surface of the second screw cover body 5012, with the second flap 5014 extending inward along the horizontal direction, and the second flap 5014 being installed along the circumferential direction of the second screw cover 501. The second flap 5014 and the upper surface of the second screw cover body 5012 form a second locking point, and the third locking structure can be locked and installed up to the second locking point. The second filter rod 5022 and the second filter barrel 5023 are both installed vertically, and the diameter of the second filter rod 5022 gradually decreases from bottom to top, while the diameter of the second filter barrel 5023 gradually increases from bottom to top. Here, the lower end of the second filter rod 5022 is connected to the upper side of the second base 5021, and the upper end of the second filter rod 5022 is inserted into the second filter barrel 5023 via the first end of the second filter barrel 5023 (i.e., the lower end of the second filter barrel 5023 in Figure 2). In this way, the gap between the second filter rod 5022 and the second filter barrel 5023 also gradually increases from bottom to top, without affecting the normal flow of water.The second filtration member 502 further includes a second connecting member 5024, which has a substantially flat structure, with a first end of the second connecting member 5024 (i.e., the lower end of the second connecting member 5024 in Figure 2) connected to the second base 5021, and a second end (i.e., the upper end of the second connecting member 5024 in Figure 2) connected to the second filtration barrel 5023, thus achieving a connection between the second filtration barrel 5023 and the second base 5021. A seventh flange 50231 and an eighth flange 50232 extend outward from the second end of the second filtration barrel 5023 (i.e., the upper end of the second filtration barrel 5023 in Figure 2), and these seventh flange 50231 and eighth flange 50232 are distributed along the circumferential direction of the second filtration barrel 5023. The eighth flange 50232 is connected to the second end of the second connecting member 5024, and the third annular boss 50233 extends upward from the upper surface of the seventh flange 50231. The fourth annular boss 1121 extends downward from the inner edge of the second through hole 112, with the outer diameter of the fourth annular boss 1121 being approximately the same as the inner diameter of the third annular boss 50233, so that when the installation is complete, the third annular boss 50233 covers the outside of the fourth annular boss 1121. When installing the second filtration component 50, the second base 5021 is first installed by locking the third locking structure to the second locking point, thereby engaging and connecting it to the second screw cover 501. Then, the second filter barrel 5023 and the second filter rod 5022 are pushed into the second water supply chamber 103, and an upward external force is applied to connect the third annular boss 50233 to the fourth annular boss 1121. Then, an external force is applied to the second handle end 5013, and the second screw cover 501 is rotated to engage and connect it to the second mounting opening 110. In this way, the second filtration component 50 is installed inside the second water supply chamber 103.

[0045] Thus, as the water flows through the first filtration member 402 and the second filtration member 502, it first catches cotton, fibers, etc. in the water with the first filtration rod 4022 and the second filtration rod 5022, and then passes through the gap between the first filtration rod 4022 and the inner wall of the first end of the first filtration barrel 4023, and the gap between the second filtration rod 5022 and the inner wall of the first end of the second filtration barrel 5023, before passing through the first drainage chamber 107 and the second drainage chamber As the water flows into chamber 108, the gap between the first filter rod 4022 and the inner wall of the first end of the first filter barrel 4023 (i.e., the lower end of the first filter barrel 4023 in Figure 2), and the gap between the second filter rod 5022 and the inner wall of the first end of the second filter barrel 5023 (i.e., the lower end of the second filter barrel 5023 in Figure 2) are both small. In this way, impurities such as gravel and peony in the water can be further filtered out, resulting in a good filtration effect.

[0046] As shown in Figures 1 to 3, and following the orientation shown in Figure 2, the height of the first filter barrel 4023 is lower than that of the second filter barrel 5023, the radial dimension of the first end of the second filter barrel 5023 is smaller than that of the first end of the first filter barrel 4023, and the diameters of the first filter rod 4022 and the second filter rod 5022 when they are at the same height are approximately the same. Thus, the gap between the second filter rod 5022 and the inner wall of the first end of the second filter barrel 5023 is smaller than the gap between the first filter rod 4022 and the inner wall of the first end of the first filter barrel 4023. Because the height of the second filter barrel 5023 is relatively high, the water flow is slowed down once it enters the second water supply chamber 103 before reaching the first end of the second filter barrel 5023 (i.e., the lower end of the second filter barrel 5023 in Figure 2), passing through the gap between the second filter barrel 5023 and the second filter rod 5022 before entering the second drain chamber 108. Furthermore, because the gap between the second filter rod 5022 and the inner wall of the first end of the second filter barrel 5023 is smaller, impurities such as gravel and pebbles in the water can be filtered more effectively. In other words, the second filtration component 50 can achieve a better filtration effect than the first filtration component 40, meaning that the purity of the water coming out of the second drain outlet 105 is higher. When using the double pump assembly of the present invention, a water channel with a higher requirement for water cleanliness may be connected to the second drain outlet 105, thereby better meeting the filtration requirements.

[0047] It should be explained that the height of the first filter barrel 4023 may be the same as the height of the second filter barrel 5023. In this case, the diameter of the first filter rod 4022 may be larger than the diameter of the second filter rod 5022 when it is at the same height. This makes the gap between the first filter rod 4022 and the inner wall of the first end of the first filter barrel 4023 smaller than the gap between the second filter rod 5022 and the inner wall of the first end of the second filter barrel 5023, thereby ensuring that the second filter component 50 has a better filtration effect. Clearly, the gap between the second filter rod 5022 and the inner wall of the first end of the second filter barrel 5023 may be the same as the gap between the first filter rod 4022 and the interior of the first end of the first filter barrel 4023. In this case, since the height of the first filter barrel 4023 is lower than the height of the second filter barrel 5023, the velocity of water flow at the first end of the first filter barrel 4023 is lower than the velocity of water flow at the first end of the second filter barrel 5023, and the filtration effect of the second filtration component 50 is also better than that of the first filtration component 40. Without departing from the principles of this application, those skilled in the art can flexibly select the specific installation configuration of the first filter barrel 4023 and the second filter barrel 5023 according to the specific application scene, as long as the double pump assembly can filter impurities from the water flowing through it.

[0048] It should be explained that the first filtration member 402 and the second filtration member 502 may be installed in other ways. For example, the first filtration member 402 and the second filtration member 502 may be installed as a filter screen or filter grill. Taking the example of the first filtration member 402 being installed as a filter screen, the filter screen is installed in the first through-hole 111, and the water that enters the first water supply chamber 102 through the water inlet 101 is filtered by the filter screen before entering the first drainage chamber 107. Without departing from the principles of this application, those skilled in the art can flexibly select the specific installation method of the first filtration member 402 and the second filtration member 502 according to the specific application scene, as long as impurities can be filtered from the water flowing through the double pump assembly.

[0049] The following describes a specific embodiment of the double pump assembly of the present invention, using a drum-type washing machine as an example, with reference to the drawings.

[0050] As shown in Figures 1 to 3, the drum-type washing machine includes a casing (not shown), within which an outer drum (not shown) and an inner drum (not shown) installed inside the outer drum are located, and the inner drum is rotatable relative to the outer drum. A double pump assembly is installed inside the casing, and its water inlet 101 is connected to the bottom of the outer drum. The drum-type washing machine includes a circulating water channel (not shown) and a draining water channel (not shown). The first end of the draining water channel is connected to the first drain port 104 of the double pump assembly by a method such as an engagement connection or hose clamp, and the second end extends outside the casing. The first end of the circulating water channel is connected to the second drain port 105 of the double pump assembly by a method such as an engagement connection or hose clamp, and the second end is connected to the top of the outer drum. In this way, while the drum-type washing machine is in operation, the inner drum rotates the clothes to be washed placed inside it, causing the clothes to be repeatedly lifted and dropped, and in combination with the action of the wash water and detergent, the clothes can be washed. At this time, the second pump head component 30 is activated, and through the action of the second pump head component 30, the water at the bottom of the outer drum enters the second water supply chamber 103 of the double pump assembly via the water inlet 101, is filtered by the second filtration component 50, enters the circulation channel via the second drain port 105, and returns to the top of the outer drum. In the dewatering stage, the first pump head component 20 is activated, and through the action of the first pump head component 20, the water in the outer drum enters the first water supply chamber 102 of the double pump assembly via the water inlet 101, is filtered by the first filtration component 40, enters the drain channel via the first drain port 104, and is discharged through the drain channel.

[0051] As shown in Figures 1 to 3, the double pump assembly further includes a mounting component 60, which includes a first mounting plate 601 and a second mounting plate 602, the first mounting plate 601 being mounted on the outside of the pump body 10, the first mounting plate 601 being substantially rectangular, the first mounting plate 601 having two positioning posts 6011 and four first screw holes 6012, the second mounting plate 602 having two positioning holes (not shown) and four second screw holes (not shown) at corresponding positions. The second mounting plate 602 has three overhanging ends 6021, each overhanging end 6021 having a third screw hole 6022. During installation, the two positioning posts 6011 are aligned into the two positioning holes and inserted into the positioning holes. Each fastening member (e.g., screw, bolt, etc.) is then inserted through the first screw hole 6012 and the second screw hole in sequence, and then tightened to fix and connect the first mounting plate 601 and the second mounting plate 602. The double pump assembly is then installed inside the drum-type washing machine casing by ensuring that each fastening member (e.g., screw, bolt, etc.) is inserted through the second screw hole and then fixed to the casing of the drum-type washing machine. It is obvious that the fastening members may be inserted through the second screw hole and the first screw hole 6012 in sequence.

[0052] It should be noted that the number of positioning posts, first screw holes, and protruding ends described above are merely illustrative. Without departing from the principles of this application, a person skilled in the art can flexibly select the specific number of positioning posts, first screw holes, and protruding ends according to the specific application scene, as long as the double pump assembly can be installed inside the housing using the first mounting plate 601 and the second mounting plate 602.

[0053] It should be noted that the first mounting plate 601 and the second mounting plate 602 may be fixedly connected by methods such as engagement connection, insertion connection, adhesive connection, or screw connection, and the second mounting plate 602 may be fixedly connected to the housing by methods such as engagement connection, insertion connection, adhesive connection, or screw connection. Without departing from the principles of this application, a person skilled in the art can flexibly select the connection method between the first mounting plate 601 and the second mounting plate 602, and between the second mounting plate 602 and the housing, depending on the specific application scene, as long as the double pump assembly can be fixedly installed inside the housing.

[0054] It should be noted that the mounting component 60 may be installed in other forms. For example, the mounting component 60 may consist only of a first mounting plate 601, with mounting holes provided in the housing that engage with positioning posts 6011 on the first mounting plate 601. In this way, the fastening members are connected to the housing after being inserted through the first screw holes 6012 by the engagement of the positioning posts 6011 with the mounting holes, thereby fixing and mounting the double pump assembly inside the housing. Alternatively, for example, the mounting component 60 may consist of two mounting pieces extending outward from the outer wall of the pump body 10, with one through-hole provided in each mounting piece. In this way, the fastening members are connected to the housing after being inserted through the through-holes, thus fixing and mounting the double pump assembly inside the housing. Without departing from the principles of this application, those skilled in the art can flexibly select the specific installation form of the mounting component 60 according to the specific application scene, as long as the double pump assembly can be installed inside the housing.

[0055] As shown in Figures 1 to 3, and following the orientation shown in Figure 3, a drain valve 113 is further installed in the pump body 10, and this drain valve 113 communicates with the first water supply chamber 102 and is located at the lowest position in the first water supply chamber 102. In this way, when the operation of the double pump assembly stops, the water in the pump body 10 is discharged via the drain valve 113 until all the water in the pump body 10 is drained, thus preventing water from remaining in the pump body 10, which would cause bacteria to multiply and generate unpleasant odors.

[0056] It should be noted that the drain valve 113 may be connected to the second water supply chamber 103. Without departing from the principles of this application, a person skilled in the art can flexibly select the specific installation location of the drain valve 113 according to the specific application scene, and the drain valve 113 should be used to completely drain the water from inside the pump body 10.

[0057] A second aspect of the present invention further provides a garment processing apparatus, which includes a double pump assembly as described in any one of the above-mentioned inventions.

[0058] It should be explained that the garment processing device has all the technical effects of the double pump assembly described above, and this will not be discussed further here.

[0059] In summary, in the preferred technical configuration of the present invention, by installing one water inlet 101, two drainage ports, and two pump head components on the pump body 10, two pumps are integrated, enabling two different, mutually non-interfering flow paths to be realized with just one pump body 10. This requires relatively little installation space, is easy to install, reduces costs, and reduces noise generated during operation. The installation of an intermediate chamber 106, a first drainage chamber 107, and a second drainage chamber 108 ensures stable operation of the double pump assembly. The installation of a first filtration component 40 and a second filtration component 50 better satisfies the water quality requirements of different water channels.

[0060] Of course, the interchangeable embodiments described above, and the interchangeable embodiments and preferred embodiments, can be used in combination with each other, thereby combining them into new embodiments and applying them to more specific application scenarios.

[0061] It should be noted that those skilled in the art can understand that some of the embodiments described herein include certain features included in other embodiments rather than other features, and that combinations of features of different embodiments belong within the scope of the present invention and mean forming different embodiments. For example, in the claims of the present invention, any one of the embodiments for which protection is claimed can be used in any combination.

[0062] So far, the technical solution of the present invention has been described in combination with the preferred embodiments shown in the drawings. It is easily understood by those skilled in the art that the protection scope of the present invention is clearly not limited to these specific embodiments. On the premise of not departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to related technical features, and the technical solutions after these changes or substitutions all belong within the protection scope of the present invention.
